So, you actually think that Disney is monitoring your every visit, purchase, park entry, fast pass, priority seating, etc.? No matter if you bought 14 park hoppers and distributed them amongst your friends and family? And if you pay with a credit card? Do they pull your prints off cash? If you ate with friends under their reservations, or just popped in last minute? Again, not enough resources and inability to get such precise information (for instance, purchases made with cash and/or credit cards, which they DO NOT have access to!) among other logical problems with this theory. If you used precisely the same name on your reservation and PS's, bought and used an annual pass or LOS pass, used your room key for every single purchase and Disney absolutely wanted to spend the time and money to make such records then they might be able to get some rough file. How often does a visitor do all those things? Not enough to make it worthwhile even if Disney could pull that info together for each. Many of us stay under someone else's name, use cash, use a park hopper pass purchased earlier, eat on impulse (with no sort of record!), etc. so that Disney might or might know be able to determine if you were even at their resort!
General stats are possible and might yield enough info to be helpful in their marketing, but there simply cannot be such explicit records on each individual. I just can't imagine why you would go to Disney if you truly believed they were maintaining such a record on you. I wouldn't.
